SEINDLE-BEARING.

To all whom it may concern:

Be it known that I, MAX MUELLER, a subject of the German Emperor andresident of Clifton, in the county, of Passaic and State of New Jersey,have invented certain new and useful Improvements in Spindle- Bearings,of which the following is a specification. p

The present invention relates to bearings for spindles of spinningmachines, and has for one of its objects to provide a simple,

efficient and inexpensive middle or bolster bearing foruse-in connectionwith the bol ster rail of the mule of a spinning machine Another objectof the invention is to provide a bolster bearing which can be easilyreplaced when worn out.

A further object of the invention is to inexpensive lubricating meanswhich fur- ,nishes a continuous stream of oil to the bearing.

With these and other objectsin View, which will more fully appear as thenature of the invention is better understood, the same consists in thecombination, arrangement and construction of. parts hereinafter port-ionof the several parts and minor fully described, pointed out in theappended claims and illustrated in the accompanying drawings, itbeingnnderstood that many changes may be made in the size and pro- 33of'Fig. 1; Fig. 1 is amodification of the invention; Fig. 5 is avertical sectional view-of a spindle and a modified bearing; Fig. 6 is aplan view thereof; ig. 7 a is a front elevation of the bolster bearing;and

stance by means of screws. 11, 11, or otherwise, a, preferably, T-shapedbolster rail 12. This rail is provided with a series of conicalapertures 13. In each of these apertures is seated the conical head 14'of a bolster bearing 15, which is made in the form of a tubular member,provided below its conical head 14 with screw threads 16, engaged by anut 17 which latter bears against the lower surface of the rail 12, andis adapted to hold the bolster bearing rigidly in its proper position,In the bearing 16 is rotatably journaled a spindle 18, the upper portion19'of the bore of the bearing being ,of a larger diameter than thespindle 18. A cylindrical oil cup 20 is attached concentrically to thespindle 18, the upper end of said cup being arranged immediately belowthe nut 17 and provided with a flange 21 bent inwardly towardthelongitudinal axis of the spindle and downwardly, for .a purpose whichwill be hereinafter described.

The bearing 15 is provided with oil passages or ducts 22, 22, whichextend through the hearing from the/outer surface thereof to the surfaceof the revolving spindle 18. An outlet passage23 leads in a downwardlyinclined direction from the enlarged bore 19 of the bearing to the outersurface of the latter, through which the oil, accumulating in theenlarged bore 19, is-a'dapted to return to the cup.

The operation of this device Normally the cup is filled with oil toreach a level above the upper oil duct 22. As the spindle rotates duringthe spinning opera-- tion, the oil c'up 'will revolvetherewith,'imparting thereby a motion to the oil contained in'the cup.The oil passes constantly through the oil ducts 22 to the surface of therevolving spindlep which carries it up into the enlarged bore 19 of thebearing;

As soon as the oil collects in this enlarged bore up to the level of theinclined return passage 23. it will flow back into the cup. It will beobserved that a continuous lubricating operation is thus automaticallyobtained, whereby an undue wear of the bolster bearing or spindle iseffectively prevented. Should, however, the bolster hearing be worn out,it can be easily replaced, as

it does not form an integral part of the rail 12. The rotary motion ofthe oil cup tends {to throw the oil by centrifugal force toward theinner face of the wall of the oil cup and Ialso' toward the upper end ofthe-latter.

leaving h'e oil cup.

4 It is to be observed that the oil cup may be easily filled during therunning of the machine, and that an entirely stainless prodr not can beobtained upon the machine provided with the present invention, for thereason that the oil cannot rise. above the level of the return passage23, and cannot come thus into contact with the thread; The oil canneither atlectthe driving cord 24 of the spindle 18, which cord remainsthus in its proper condition to give an evendrive. I

shown in Fig. 4 of the drawings, in which case it is provided with screwthreads 25' below its conical head 26, said screw threads meshing withthreads 27 in the rail 12.

A further modification of the device is shown in Figs. 5 to 8,inclusive, in which the rail 12 is provided with conical seats 28, towhich lead slots 29 from the outer edge engaging the nut 33 from thethreads of the bearing, the latter together with the spindle canloo-easily taken off the rail, for instance,

in order to refill the cup with oil or to clean the oil ducts and returnpassage in the hearing. The oil cup is made in this case of two parts,and consists of a cylindrical vessel 35, fixedly attached to the spindle18,' and of a part 36, held upon the cylindrical vessel in any suitablemanner, said part 36 being provided with an inwardly and downwardlyextending flange 37 for the purpose described in connection with Figs.1.to- 3,

inclusive, of the drawings. The operation, of this device is in allrespects identical with that described hereinbefore.
